Instead of duplicating the code for user creatable objects in secret and secret_keyring, move it to the common base clase secret_common. As the base class is abstract, it won't become user creatable itself. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
